TO ALL WHOM IT MAY CONCERN:

Be it known that I, FRANcIs A. STERRY, of Canton, in the county ofNorfolk, and State of Massachusetts,

have invented a. new and improved Adiustablospind le for SpinningFrames; and I do hereby declare thatthe following is a full, clear, andexact description thereof.

The object of my invention is to obviatethe diflic'ulties which havehitherto been experienced in keeping the spindle of ring spinning framesplumb, in consequence of the wearing away of the spindle bolster andstep; and the invention consists in providing for: the adjustment ofboth the spindle bolster and the spindle step, and in securing them inany desired position, as will be hereinafter described. And to enableothers skilled'in the art to make and use my invention, I will proceedto describe its construction and operation, reference being had to theaccompanying drawing, which forms a part :of this specification, and tothe lettters of reference marked thereon. p

Figure 1 represents a longitudinal section ofa spinning frame, partlysectional.

Figure 2 is a top-view of the ring on the ring rail.

Similar letters of reference indicate like parts.

A is the step rail; 13 is the bolster rail; 0 is the ring rail; D D arethe standards; F. is the bolster; G is the step'; H is the ring. In thisexample of my invention the ring rail, G, is made fast to the top of thestandards, D D, which extend up through and above the bolster railforthat purpose. ,This

arrangement is only for convenience in demonstrating my invention, as itis well known that the, ring-rail is attached to lifting-rods, whichgive it a vertical motion when the frame is in use. The difiiculty whichhas hitherto been experienced has been in keeping the spindle plumb andin the centre of the ring, H, which is placed in the centre of the ringrail. This ring is fast inthe rail, and usually secured by a set-screw.In order that the thread from the spindle may run in the properdirection, and to avoid extra labor, it is necessary that the spindleshould stand plumb and in the centre of the ring otherwise the thread isliable to break, and'the 'is' constantly pulling the spindle in onedirection, and the bolster (whichis the spindle-box) is consequentlyworn on one side only; and as the bolster wears, thespindle is thrownout of makes the trouble and causes the extra labor. The same cause isconstantly operating on, the ,bottom end'of the spindle, wearing thestep on one side, and consequently throwing the spindle out ofplunib andfrom' the I centre of the ring, thereby causing the same trouble asbefore mentioned. Under these circumstances the usual remedy is to putin a new bolster, or a new step, or both. New, I obviate the difiicultywithout doing either; by simply adjusting the spindle to its trueposition, manner: The bolster, F, has a broad shoulder, a, which restsupon the topof the rail, B. The lower portion, or end below the rail,has a nut,f, on it. That portion of the bolster which rests in the holethrough the rail is made smaller than the hole, which allows the bolsterto be moved and the spindle to be adjusted in any desired position; andwhen the spindle is placed in the centre of the ring, nut, f. The step,G, is constructed in the same manner, with a shoulder, to rest on therail, and ,a nut, g, on its bottom end, under the rail. The centralportion has room for adjustment in the hole, through tho'rail, theposition in the same manner by the nut, 'g. The space around the bolsterand around the step, which allows of this adjustment, is indicated by 0in the drawing is a collar or flange on the spindle, upon which thespool rests, and the pins, 0, enter the bottom end of the spool,and'couple the spool to the spindle. i

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- Adjusting the spindle E, by the bolsterF, the step G, nuts f g, and openings 0 O, substantially in the mannerand for the purposes herein set forth.

The above specification of my invention signed by me this 5th day ofSeptember, 1866.
